A density version of quaternary Goldbach problem

Xiaoyang Hu, Meng Gao

Let $P$ denote the set of all primes, and let $I^´ (P)$ denote the relative lower density of a subset $P$ in $P$ . Suppose that $P_{1}, P_{2}, P_{3}, P_{4}$ are…

On the quadratic Waring-Goldbach problem with primes in Piatetski-Shapiro sets

Meng Gao, Jinjiang Li, Linji Long +1

In this paper, it is proved that, for any $I^_{1}^{3}, I^_{2}^{3}, I^_{3}^{3}, I^_{4}^{3}, I^_{5}^{3} \in (\frac{28}{29}, 1)$ , every sufficiently large integer $n$ subject to $n \equiv 5 (mod 24)$ can be represented as…
